Zero point motion and direct/indirect bandgap crossover in layered transition-metal dichalcogenides
L. Ortenzi, L. Pietronero, E. Cappelluti
Two-dimensional transition-metal dichalcogendes (es. MoS, WS, MoSe, \ldots) are among the most promising materials for bandgap engineering. Widely studied in the…

Extended Drude model and role of interband transitions in the mid-infrared spectra of pnictides
L. Benfatto, E. Cappelluti, L. Ortenzi +1
We analyze the outcomes of an extended-Drude-model approach to the optical spectra of pnictides, where the multiband nature of the electronic excitations requires a careful analysi…

Fermi surface shrinking and interband coupling in iron-based pnictides
L. Ortenzi, E. Cappelluti, L. Benfatto +1
Recent measurements of Fermi surface with de Haas-van Alphen oscillations in LaFePO showed a shrinking of the Fermi pockets with respect to first-principle LDA calculations, sugges…
